Working Principle

A fixed inductor is an electrical component that comprises of a coil of tightly wound wire. It can be thought of as a permanent electrical generator, as it produces an electromotive force (EMF) when current flows through the coil. The EMF is proportional to the rate of change in current, which results in induced voltage drop. The value of the induced voltage drop is known as inductance (L in henries), which resists any change in current.

The value of the inductance is dependent on the shape and material of the coil, as well as the number of turns in the winding. The Panasonic ER1641-303JP uses an iron core, which increases its coefficient of inductance (CL). The CL of the Panasonic ER1641-303JP is consistently low, which is necessary for its wide range of application fields.

Conclusion

The Panasonic ER1641-303JP is a popular shielded, low-profile fixed inductor. Its compact form factor, extended work frequency, consistently low DCR, and wide range of inductance and heat resistance makes it suitable for a wide range of applications, such as switching power supplies, chip on board applications, and printed circuit board designs. The working principle of the device involves an electromotive force, generated in the coil of the inductor, which creates an induced voltage drop that is resumed as inductance.
